Sherlock watched as the suspect got out of the cab and paid off the driver. It would be significantly easier to follow him on foot, he thought with some relief. Having got his breath back, he crossed the road, mingling with the busy Saturday night party crowd, keeping his distance and his eyes on the prize.
The man disappeared through the doors of a club and Sherlock quickly followed. The place was fairly busy but the night was still young and not as packed as it would be later. He spotted the suspect easily and watched as he bought a drink and went to sit down at a booth in the corner with two other people, clearly friends of his judging by the way they greeted him.
Sherlock approached the bar and sat down on one of the high up stools, in a suitable position where he could keep his eyes on the suspect and his friends but not be seen himself, unless they actively chose to turn round and look back at the bar. He ordered himself a glass of coke and got some money out, vaguely aware out of the corner of his right eye that he was being watched by another man sat at the bar.
